The pests and diseases of wolfberry trees are a big problem, how to control the diseases and pests o

At the end of August and the beginning of September, it is the peak period for the occurrence of wolfberry gall mites. Goji barbarum gall mites damage the leaves, flower buds, young fruits, young stems, petals and flower stems of wolfberry, after being harmed, the flower buds can not flower and bear fruit, the leaf surface is not smooth, the whole wolfberry tree grows weakly when it is serious, and the fruit falls leaves, resulting in reduced yield, seriously affecting the yield and quality of wolfberry. Lycium barbarum is the main leaf-eating pest of Lycium barbarum, mainly harming the leaves of Lycium barbarum, and the larvae are more serious than the adults.

If the bud of wolfberry is harmed, wolfberry will not be able to branch and leaf normally. The garden should be built in a place with loose and fertile soil, good drainage, open terrain and good lighting. From late autumn to early spring, combined with field management measures such as pruning, ploughing, and basal fertilizer, the fallen leaves, weeds and diseased residues in the garden are completely removed, and buried or burned in a centralized manner.

The serious harm is that the annual mortality rate of plants suffering from this disease is 3% to 5%, which brings great losses to wolfberry production. The disease mainly harms the rhizomes and roots of wolfberry, which is brown to black-brown in the early stage of the disease, and then gradually decays, and peels off in the later stage, leaving only the xylem, and the vascular brown can be seen when the diseased stem is cut.

When the humidity is high, a layer of white to pink mycelium appears in the affected area. The aboveground leaves are yellowed or the branches are shriveled, and in severe cases, the branches or the whole plant die. The planting of wolfberry should not be too dense, and the dense branches should be thinned in time to ensure ventilation and light transmission in the garden.

Lycium barbarum root rot is easy to cause the death of wolfberry plants, resulting in economic losses, the disease mainly harms the rhizome and root system of wolfberry, it is brown to black-brown in the early stage of the disease, gradually decays in the later stage, peels off in the later stage, leaving only the xylem, and the vascular bundle of the diseased stem is brown. Pink hyphae also appear in high humidity. The leaves are yellow, and the branches die severely.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

We should do a good job in the field management of wolfberry trees, prune the corresponding branches at the beginning of spring, water them on time, achieve the best water supply, and when the wolfberry trees begin to sprout, they should be sprayed with pesticides regularly, and they should be sprayed once every 15 days, so as to prevent pests and diseases, ensure sufficient sunlight, and reduce the occurrence of pests and diseases.

It can be timely insect removal, weeding, to ensure that the drainage is good and timely watering, to choose high-quality seedlings, in the soil is fertile, sunny place for planting, when found germs, to prune in time to prevent the impact on other branches.

In early spring and late autumn, clean up the pruned residues, wilts, diseases, and insect branches in time, together with the dry grass and leaves around the garden, and burn them outside the garden to eliminate the source of insects.

Timely fertilization, frequent sterilization and disinfection, spraying nutrient solution, a certain amount of sunshine, and scientific management.

Be sure to prevent pests and diseases, spray pesticides, and use high-quality seeds from the start.
